UNITED STATES PATENT OFFICE.

C. VANDERBILT DECKER, OF NEW SPRINGVILLE, NEW YORK.

SHIPS PUMP.

SPECIFICATION forming part of Letters Patent No. 225,353, dated March 9,1880.`

Application filed December 30, 1879.

4of New Springville, Staten Island, State ot' New York, have invented anew and useful Improvementin Ship-Pumps, of which the following is aspecification.

In ship-pumps the suction has to be taken either from one side or fromthe other side of the vessels pipe, or, in some cases, from both sidesat one and the same time. For this purpose cocks have usually beenarranged whereby this object can be obtained; but this ar'- rangement isvery objectionable on account of the sea-water affecting the metal andmaking the cocks very soon leaky, besides the danger from themultiplicity of the joints.

My improvement consists in the arrangement and construction of avalve-chamber which contains the valves for changing` easily thesuction, and which support the pump-barrels, and at the same time toprovide this chamber or pump'bottomA with suitable openings for tryingreadily the depth of water in the vessels hold or in the suction-pipes.

In the accompanying drawings, Figure 1 represents a vertical section ofthe chamber or pump-bottom embodying my invention. Fig. II is a plan ofthe same with the cover removed.

Similar letters represent similar parts.

A is the bottom of the pump, att-ached to the deck of the vessel,provided with bottom branches b b', to which the suction-pipes leadingdown into the hold of the vessel are attached. Directly above thesebranches b b tubes c c are arranged, closed by screw-bolts or caps d d',for the purpose 'of trying the depth of water in the hold of the vesselat any time. The bottom or under side of the chamber-cover B makes atight joint upon the ends ot' these tubes c c.

The branches b bconnect with passage-ways u* fw', made in the chamberA., separated through the division-plate c. Into each of these passagesan opening, n or fn', is made, closed with suitable valves 'm m',operated, by means of suitable screw valverods h h', from the outside ofthe chamber A.

The water drawn through either of the suction-pipes passes through thevalve-openings into the body ot' the chamber, and then, through apassage-way, S, into the pumpbarrels P P', attached to the cover B,andarranged and operated in the usual manner.

The lifting-valves m m are provided with an india-rubber or othersuitable facing, to insure a tight joint on the face ot' thevalve-seats.

What l claim as my invention, and desire to secure by Letters Patent,is-

For ship-pumps, the chamber A, with passages w fw', connecting with thesuction-pipes b b', and openings n n', closed by lifting-valves, incombination with the try-tubes c c and pumps P P, arranged in the mannerand for the purpose substantially as described.
